Chifukwa chakuchulukirachulukira kwa zida zotayira-zotulutsa, makina otayira{1}akufunika kugwira ntchito kwa nthawi yayitali. Tikuwona kuti ngakhale ndinu woyamba kapena wakale, nthawi zambiri mumakumana ndi zovuta mukamagwiritsa ntchito zida zamafakitale izi poponya kufa. Pakati pawo, nyundo kumamatira ndi vuto lomwe nthawi zambiri limakumana nalo. Kodi mungapewe bwanji nyundo kuti isamamamire?
Pofuna kupewa nyundo kuti isamamamire panthawi yoponya kufa, titha kuyambira pazifukwa ziwiri izi:
1. Pamene kufa akuponya workpieces, mukhoza nthawi zambiri kuyang'ana kutentha kwa zipangizo mafakitale, makamaka kutentha kwa nyundo ndi manja. Zikadziwika kuti kutentha kwakwera kwambiri, muyenera kuchitapo kanthu kuti muchepetse kutenthako, chifukwa kutentha kwa nyundo ndi manja kukadutsa momwe zimagwirira ntchito, nyundoyo imatha kukakamira.
2. Mukamagwiritsa ntchito ma die casting, samalani posankha -zapamwamba kwambiri-zopangidwa ndi aloyi, musalole zotsalira zilowe muzopangira, ndipo mukamafa, samalani kuti zotsalirazo zilowe m'malo momwe zimapangidwira kuletsa zotsalira kumamatira ku nyundo ndikupangitsa nyundo kuti ipunthwe.
Pofuna kuwonetsetsa kuti makina otayira-akhoza kugwira ntchito moyenera komanso mosasunthika, m'pofunikanso kulabadira zotsatirazi panthawi ya ntchito:
1. Mukafa-kuponya nkhungu zotentha, mutha kugwiritsa ntchito aloyi ya aluminiyamu yamadzimadzi kuti mufe-kuponya zotentha pang'onopang'ono kwa 5-10, kenako mutha kufa-kuponyedwa ndi semi-solid aluminium alloy ndi semisolid{7} kufa{{9}kuponya. Cholinga chochitira izi ndikuteteza nkhungu ndikuletsa zinthu zowuluka kuti zisachitike panthawi yakufa.
2. Kuti muteteze chizindikiro cha RF cholumikizira ndi kutumizirana mauthenga kuti zisakhudzidwe panthawi ya ntchito, zomwe zimabweretsa zolakwika za chizindikiro ndi ngozi, muyenera kumvetsera momwe chizindikiro cha RF cholumikizira ndi cholumikizira chosinthira. Opaleshoniyo ikamalizidwa, onetsetsani kuti mwathimitsa chosinthira chachikulu ndikuchotsa magetsi.
Malinga ndi chifukwa cha kupanikizana kwa hammer pa nthawi ya kufa-kuponyera makina a kufa{1}}kuteteza koyenera kumachitidwa. Tikukhulupirira kuti wogwiritsa ntchitoyo atchera khutu kangapo mufafa-m'chipinda chopangira makina kuti achulukitse moyo wautumiki wa makina otayira akufa{4}}.
